IMPROVEMENT IN WEIGHING-SCALES.

Specification forming part of Letters Patent N 0. 201,984, dated April'2, 1878; application filed February 9, 1678.

To all whom it may concern.-

Be it known that I, CONRAD BERsT, of of Kosciusko and State of Indiana,have invented certain new and useful Improvements in Weighing-Scales andI do hereby declare the following to be a full, clear, and exactdescription thereof, reference being had to the accompanying drawing,and to the letters of reference marked thereon.

The nature of my invention relates to weighing-scales and it consists inthe construction and arrangement of a platform suspended at its endsfrom two elevated separate and independent levers, the inner ends ofwhich are connected to a scale-beam, all as hereinafter more fully setforth, and pointed out in the claim. A

' In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, whichforms a part of this specification, and in which- Figure 1 is alongitudinal vertical section of my weighing-scales, and Fig. 2 is aplan view thereof. Figs. 3 and 4 are sectional details.

A represents a bed-frame of any suitable dimensions, within which theplatform B is allowed to move freely the required distance up and down,and also have sufficient play both longitudinally and laterally.

From each end of the bed-frame A rise two standards, 0 O, which inclinetoward each other, and are united at their upper ends. These standardsat the two ends of the bedframe are connected at their upper ends by D,which are placed a suitable distance apart, and thus run longitudinallyabove the center of the frame and platform.

On the beams D D are two vertical posts,

b l), in which is hung the scale-beam F by means of the rod or journals(1. The scalebeam F is provided with the usual sliding poise E, and atits outer end with the hook or its equivalent G, for the attachment ofweights. On the inner end of the scale-beam is the adjustablebalancing-poise H.

In the inner end of the scale-beam is fastened a link, (I, through whichis passed a double hook, e, and upon each end of said hook is attached alink, 71 The links h h are attached to the inner ends of two levers, II, which are placed between the beams D D, and their outer ends formedin the shape of a T. The ends of the T-arms are placed in boxes orbearings J J attached to the ends of the beams D D, as shown.

It will, of course, be understood that the bearings for the levers I I,as well as for the scale-beam, are made in the usual knife-edge form.

From each lever I, a suitable distance inward from its outer end, isdepending a link,

m, in which are attached two rods, n a, fast ened in the corners of theplatform B. The platform thus becomes suspended from two separate andindependent levers, and acting upon a single scale-beam.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

The combination, with a bedframe, A, standards 0, and beams D D, of theplatform B, rods n a, links m m, levers I I, scale-beam F, andconnections cl 0 h between the scalebeam and the inner ends of thelevers, all substantially as herein set forth.

CONRAD BERST.
